Mineral regeneration mechanics are changed. Mineral regeneration amount is no longer random, but rather depends on a new property called Mineral.density:
DENSITY_LOW: 15K amount (10% probability)
DENSITY_MODERATE: 35K amount (40% probability)
DENSITY_HIGH: 70K amount (40% probability)
DENSITY_ULTRA: 100K amount (10% probability).
It gives the same average value as before this change, but now it is predictable and creates some variety between rooms.
In most cases, density is not changed between regenerations. However, there is a 5% chance that it will be changed to a random new density on the next regeneration cycle. For DENSITY_LOW and DENSITY_ULTRA deposits this chance is always 100%.
Mineral deposits density is visually observable on the world map using the corresponding display option.
Flags count is now limited to 10,000 per player.
When created via the API, flag names are limited to 60 characters (creating via UI is already limited, there was the lack of filtration in the API). Old flags names will be truncated to 60 characters.
When remainingAmount property of a market order becomes equal to 0, the order now does not get deleted, but becomes inactive instead. You can call extendOrder and reactivate it keeping the same persistent ID. You must call cancelOrder explicitly in order to remove this order from your list.
